Each record captures the characteristics of
one energetic neutral atom arriving at IBEX-Hi. Included is a
time tag (seconds since 00:00 UT of January 6, 1980), an arrival
direction (R.A. and Dec. in J2000 celestial coordinates), the IBEX
location, ENA energy band and coincidence type. Positive species
identifications are not made, but most arriving ENA's are hydrogen
atoms. Data files are given for each 8-day orbit and for each
of the 6 IBEX-Hi energy bands. The data files are in ASCII.

Each record captures the number of arriving ENA's
of a specific energy band, coincidence type, and spin phase. Data
for each full ~15s spacecraft spin are given at each of 60 spin
phases in sequential records, with the J2000 right ascension and
declination for look directions corresponding to each spin phase
being given in the corresponding record. Also included in each
record are a time tag (seconds since 00:00 UT of January 6, 1980),
the IBEX location, ENA energy band and coincidence type. Positive
species identifications are not made, but most arriving ENA's are
hydrogen atoms. Data files are given for each 8-day orbit and for
each of the 6 IBEX-Hi energy bands. The data files are in
ASCII.

As of this writing (11/5/2010), this product
had been issued by the IBEX team in two releases.
Release 1 IBEX-Hi map data are superseded by Release 2
data which are more time-extensive (12 months vs. 6 months)
and are richer in content. While Release 1 IBEX-Hi map data
and their documentation remain accessible at
ftp://spdf.gsfc.nasa.gov/pub/data/ibex/hi/maps/digital_data/release_1/
and
ftp://spdf.gsfc.nasa.gov/pub/data/ibex/hi/maps/images/release_1/,
this description supports the retrieval and use of Release 2 data only.
The Release_2 IBEX-Hi map data contain all-sky 6 deg x 6 deg
resolution maps in J2000 ecliptic coordinates of energetic
neutral fluxes reaching the near-Earth IBEX spacecraft from
the distant heliosphere and heliosheath. Maps
are in both a spacecraft frame and, via Compton-Getting
corrections, a heliospheric frame. Basic maps are each
accumulated over 6-months duration, so far for epochs 1
(12/2008-06/2009) and 2 (06/2009-12/2009). Maps are available
for five of the energy bands of IBEX-Hi (0.52-0.95, 0.84-1.55,
1.36-2.50, 1.99-3.75, 3.13-6.00 keV) and, for the heliospheric
frame only, also for six monoenergetic points (0.71, 1.11, 1.74,
2.73, 3.0, 4.29 keV). In addition, monoenergetic maps are available
as summed over the data collected during epochs 1 and 2 combined.
All maps are available in digital text format and in PNG image format
(considered as separate data sets within VEPO).
Given that VHO/VEPO typically displays clickable granule (file)
names for any given specification of data product and time span,
and given that IBEX-Hi digital maps and PNG-formatted display
maps are each considered single data products, a request for data
from either product will yield .GE.20 names of files containing data
spanning or within the requested time span. For IBEX, the names
shown by VHO/VEPO actually have the form subdirectory/filename.
The subdirectories are named map1, map1cg, map2, map2cg, and
map-combined. Maps involving "1" ("2") are from the first (second)
6-month epoch, while "combined" means composed of data taken
during epochs 1 and 2. Maps involving (not involving) "cg" means
heliospheric frame (spacecraft frame). In the first four subdirectories,
file names are of the forms ha60.hide-trp-flux100-hi-N-flux.ext and
ha60.hide-trp-mono_80-P.PP-flux.ext, where "ext" is "png" or "txt"
according to which product is requested, N is the energy step
number for the IBEX-Hi instrument (2-6), P.PP is the energy level,
in keV, of a monoenergetic flux. Files in the "combined"
subdirectories are named "combined-P.PP-flux.ext, where P.PP
has the same meaning as above.
In addition to the flux maps to which VEPO provides access,
several map files whose data support the determination of the
fluxes are also available in the underlying nssdcftp directories
and are described by aareadme files there (and by IBEX web pages
at SWRI: http://ibex.swri.edu/ibexpublicdata/Data_Release_2/)

Each table (CSV file) captures the numbers
of counts of arriving energetic neutral atoms, as integrated
over a full 8-day orbit, for a single IBEX-Lo energy step,
for one of two categories of species (hydrogen, oxygen plus
carbon, the latter being labelled "Oxygen" in file names).
Numbers of counts are given in 360 1-degree bands in
spacecraft spin phase. Each table is CSV-formatted Excel.
Each subdirectory is for a given energy band and has the
tables (files) for each of several orbits for each of the two
species categories.

Each record captures the characteristics of
one energetic neutral atom arriving at IBEX-Lo. Included is a
time tag (seconds since 00:00 UT of January 6, 1980), an arrival
direction (R.A. and Dec. in J2000 celestial coordinates), the IBEX
location, ENA energy band, species (hydrogen or oxygen) and
coincidence type. Data files are given for each 8-day orbit and
for each of the 8 IBEX-Lo energy bands. The data files are in
ASCII.

Each record captures the number of arriving ENA's
of a specific energy band, coincidence type, species (hydrogen or
oxygen) and spin phase. Data for each full ~15s spacecraft spin
are given at each of 60 spin phases in sequential records, with
the J2000 right ascension and declination for look directions
corresponding to each spin phase being given in the corresponding
record. Also included in each record are a time tag (seconds since
00:00 UT of January 6, 1980), the IBEX location, ENA energy band,
species and coincidence type. Data files are given for each 8-day
orbit and for each of the 8 IBEX-Lo energy bands. The data files
are in ASCII.

Hydrogen ENA fluxes in each of three IBEX-Lo energy
bands in each of 21,600 [720(longitude) by 30(latitude)] bins,
accumulated over 6 months. Bins are defined in J2000 ecliptic
coordinates. Maps are available for energy bands 5 (209 eV),
6 (439 eV), and 7 (872 eV). PNG-formatted image files are 24 KB
in size. Digital versions of these images in txt format are
identified by VEPO as a separate data product.

This product contains counts accumulated in
each of 30 6-deg spin phase bins over some variable time span
indicated in each record. The time spans are selected to support
analysis of the flow latitude of the interstellar medium (ISM).
The data are specifically as used in the analyses reported in
Bzowski et al (2012) and Mobius et al (2012). A companion product
has the counting data used in the ISM flow longitude analyses of
the same papers. Data are organized into orbit-specific arrays
wherein the columns contain the counts for a given time span
within the orbit and the rows contain the counts for a given one
of the 30 spin-phase angles for the multiple time spans of the orbit.
Arrays are available for orbits 12-19, 60, 61, and 63-67. The number
of time spans used in an orbit varies from 5 to 38.
